Die Trying

Sir John Franklin, 1845-48. All 139 men in the expedition died while trying to find the Northwest Passage.

George Washington De Long, 1879-82. His steamship, Jeannette, drifted for 16 months in the Bering Strait before being crushed by ice; 12 men survive.

Salomon August Andree, July 1897. Andree and two others died of exposure in their hydrogen balloon before they could reach the Pole.

Dominick Arduin, April 2004. Disappeared after dropping into open water. (The book "The Secrets of the Adventurer" by Sven Pahajoki, questions whether Arduin faked her death.)
